ABB TU810V1 16-Channel 50 V Compact Module Termination Unit for S800 I/O

Product Overview

When industrial control systems require reliable field wiring connections, the ABB TU810V1 delivers a compact and passive termination solution for the S800 I/O family. This 16-channel module termination unit (MTU) handles up to 50 V and simplifies installation by consolidating field signals and process power connections into a single unit.

Technical Specifications

The TU810V1 supports up to 16 channels with a maximum current of 2 A per I/O channel and 5 A per process connection. It accepts solid wires from 0.2 to 4 mm² and stranded wires from 0.2 to 2.5 mm² (24–12 AWG). The dielectric test voltage is 500 V a.c. Operating temperature ranges from 0 to +55 °C (+32 to +131 °F), with vertical mounting limited to 40 °C (104 °F). Storage temperature spans -40 to +70 °C (-40 to +158 °F). The unit measures 64 mm wide (including connector), 64 mm deep (including terminals), and 170 mm high (including latch), weighing 0.17 kg (0.37 lbs).

Industry Applications

In process automation and discrete manufacturing, the TU810V1 connects field devices such as sensors and actuators to S800 I/O modules. Its mechanical keying prevents insertion of incorrect I/O modules, reducing wiring errors and downtime. The compact design fits space-constrained panels, while DIN rail mounting simplifies installation and grounding via a latching device.

Installation & Setup

Mount the TU810V1 on a DIN rail in either horizontal or vertical orientation. Use the two mechanical keys to configure the MTU for different I/O module types—each key has six positions, offering 36 configurations. Connect field wiring to the terminal block, ensuring wire sizes meet the acceptable range. The MTU distributes the ModuleBus to the I/O module and to the next MTU, generating the correct address by shifting outgoing position signals.

Maintenance & Reliability

Regular inspection of connections and the DIN rail latch ensures reliable grounding and signal integrity. The TU810V1 operates in environments with pollution degree 2 (IEC 60664-1) and corrosion protection ISA-S71.04 G3. It complies with CE, electrical safety standards (EN 61010-1, UL 61010-1), and hazardous location certifications (C1 Div 2 cULus, C1 Zone 2 cULus, ATEX Zone 2). Marine certifications include ABS, BV, DNV-GL, and LR.

Compatibility & Integration

The TU810V1 works with a wide range of ABB S800 I/O modules including AI810, AI815, AI820, AI830, AI830A, AI835, AI835A, AI845, AO810, AO810V2, AO815, AO820, AO845, AO845A, DI810, DI811, DI814, DI830, DI831, DI840, DI880, DI885, DO810, DO814, DO815, DO840, DO880, DP820, and DP840. It supports single I/O configurations and provides two process power connections (2 x 2) and five process power connections (5 x 2) at 0 V.
